I'd like to know if it is possible to create a Vertex that requires an edge in order to be created.

For example, I want to create an Invoice class that has a HasCustomer edge which points to Person.

I want the HasCustomer edge to be mandatory in order to create the Invoice.

You cannot create the Invoice unless you have the HasCustomer edge.

I know we can have a link to Person, but there is no referential integrity. I can delete the Person and the Invoice will simply end up with a link to a customer that is non-existent.
